ServicesAllowedList usage guide
When the Bluetooth/ServicesAllowedList policy is provisioned, it will only allow pairing and connections of Windows PCs and phones to explicitly defined Bluetooth profiles and services. It's an allowed list, enabling admins to still allow custom Bluetooth profiles that aren't defined by the Bluetooth Special Interests Group (SIG).
- Disabling a service shall block incoming and outgoing connections for such services
- Disabling a service shall not publish an SDP record containing the service being blocked
- Disabling a service shall not allow SDP to expose a record for a blocked service
- Disabling a service shall log when a service is blocked for auditing purposes
- Disabling a service shall take effect upon reload of the stack or system reboot
To define which profiles and services are allowed, enter the semicolon delimited profile or service Universally Unique Identifiers (UUID). To get a profile UUID, refer to the Service Discovery page on the Bluetooth SIG website.
These UUIDs all use the same base UUID with the profile identifiers added to the beginning of the base UUID.
Here are some examples:
Example of how to enable Hands Free Profile (HFP):
BASE_UUID = 0x00000000-0000-1000-8000-00805F9B34FB
| UUID name | Protocol specification | UUID |
|---|---|---|
| HFP(Hands Free Profile) | Hands-Free Profile (HFP) * | 0x111E |
Footnote: * Used as both Service Class Identifier and Profile Identifier.
Hands Free Profile UUID = base UUID + 0x111E to the beginning = 0000111E-0000-1000-8000-00805F9B34FB
Allow Audio Headsets (Voice):
